Relative likelihood for life as a function of cosmic time

Abstract:

Is life most likely to emerge at the present cosmic time near a star like the Sun? We address this question by calculating the relative formation probability per unit time of habitable Earth-like planets within a fixed comoving volume of the Universe, dP (t)/dt, starting from the first stars and continuing to the distant cosmic future. We conservatively restrict our attention to the context of “life as we know it” and the standard cosmological model, ΛCDM. We find that unless habitability aro...
